To soften hard towels, add baking soda to the regular amount of laundry detergent used to wash the towels, pour 1 cup of vinegar into the wash, and dry the towels in the dryer with clean tennis balls or a dryer ball. The process takes a couple of hours.
- Add baking soda to the laundry detergent
Measure the normal amount of laundry detergent needed to wash the load of towels, and add 1/2 cup baking soda to the laundry detergent. Start the washing machine, and let the detergent and baking soda dissolve in the water before adding the towels.
- Use vinegar
Vinegar removes chemicals and hard water from the towels and softens the fibers. Pour 1 cup of white vinegar into the wash with the laundry detergent and baking soda, and then add the towels when the blades begin to rotate.
- Dry the towels with tennis balls
Place a few new tennis balls in the dryer with the wet towels. Alternatively, you may purchase a dryer ball from the grocery store. The balls bounce around in the dryer and fluff the towels as they tumble through the drying cycle. Remove the towels from the dryer, and shake them before folding them to fluff them up even more.
